Gemmae are present in :

Gemmae are tiny, multicellular propagules that serve as a means of asexual reproduction in certain non‑vascular plants.

These structures are typically produced in cup‑shaped depressions called gemma cups on the dorsal surface of the thallus. When raindrops strike the cups, the gemmae are dislodged and dispersed to new locations, where they can develop directly into a new gametophytic plant.

Among the plant groups listed, gemmae are characteristic of some liverworts, which belong to the bryophyte division. Liverworts possess these specialized asexual bodies, whereas gymnosperms, mosses, and pteridophytes do not produce gemmae as part of their reproductive strategy.

Therefore, the correct answer to the question “Gemmae are present in :” is Some Liverworts.
